整合ssm前期準工做

　　1配置好maven軟件以及maven本地倉庫

　　　　1.1maven軟件官網下載便可　　連接http://maven.apache.org/ 點擊下載css

下載這款便可

解壓到根目錄下完成java

1.2配置本地倉庫

連接：https://pan.baidu.com/s/1E6cqODfAeZgd2UtSF2FQww
提取碼：z7am
複製這段內容後打開百度網盤手機App，操做更方便哦--來自百度網盤超級會員V1的分享文件解壓後即爲本地倉庫mysql

打開D:\apache-maven-3.6.3-bin\apache-maven-3.6.3\conf下的settings.xml文件web

編輯 <localRepository>/path/to/local/repo</localRepository>spring

例如個人本地倉庫在d盤下的D:\apache-maven-3.6.3-bin\repository_bootsql

則配置以下<localRepository>D:\apache-maven-3.6.3-bin\repository_boot</localRepository>數據庫

1.3配置遠程倉庫

<mirrors>
express

<mirror>
<id>jboss-public-repository-group</id>
<mirrorOf>central</mirrorOf>
<name>JBoss Public Repository Group</name>
<url>http://repository.jboss.org/nexus/content/groups/public</url>
</mirror>apache

<mirror>
<id>nexus-aliyun</id>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>api

<mirror>
<id>repo2</id>
<name>Mirror from Maven Repo2</name>
<url>http://repo2.maven.org/maven2/</url>
<mirrorOf>central</mirrorOf>
</mirror>

將maven集成到idea中完畢

2.下載tomcat

修改D:\apache-tomcat-9.0.41\conf\logging.properties文件中的全部的UTF8改成GBK

將idea file encodeing改成utf-8發佈項目時不會出現中文亂碼的狀況

3.建立數據庫表

create database ssm;
use ssm;
create table account(
id int primary key auto_increment,
name varchar(100),
money double(7,2)
);

準備工做完成接下來建立項目

步驟：

1建立maven工程選擇webapp骨架

　　　爲避免建立項目時過慢在Properties中添加 archetypeCatalog 　　 internal 以下圖

建立完項目後添加應有的類

結構以下

  1 package com.ssm.controller;
  2 import com.ssm.service.AccountService;
  3 import org.springframework.beans.factory.annotation.Autowired;
  4 import org.springframework.stereotype.Controller;
  5 import org.springframework.web.bind.annotation.RequestMapping;
  6 @Controller
  7 @RequestMapping("/account")
  8 public class AccountController {
  9     @Autowired
 10     private AccountService accountService;
 11     @RequestMapping("/findAll")
 12     public String findAll(){
 13         System.out.println("表現層  全部信息");
 14         accountService.findAll();
 15         return "list";
 16     }
 17 }
 18 
 19 
 20 package com.ssm.dao;
 21 
 22 import com.ssm.domaiin.Account;
 23 import org.apache.ibatis.annotations.Insert;
 24 import org.apache.ibatis.annotations.Select;
 25 import org.springframework.stereotype.Repository;
 26 
 27 import java.util.List;
 28 
 29 @Repository
 30 public interface AccountDao {
 31     @Select("select * from account")
 32     List<Account> findAll();
 33 @Insert("insert into account(name,money) values(#{name},#{money})")
 34     void saveAccount(Account account);
 35 }
 36 
 37 
 38 package com.ssm.domaiin;
 39 
 40 import java.io.Serializable;
 41 
 42 public class Account  implements Serializable {
 43     private Integer id;
 44     private String name;
 45     private Float money;
 46 
 47     @Override
 48     public String toString() {
 49         return "Account{" +
 50                 "id=" + id +
 51                 ", name='" + name + '\'' +
 52                 ", money=" + money +
 53                 '}';
 54     }
 55 
 56     public Integer getId() {
 57         return id;
 58     }
 59 
 60     public void setId(Integer id) {
 61         this.id = id;
 62     }
 63 
 64     public String getName() {
 65         return name;
 66     }
 67 
 68     public void setName(String name) {
 69         this.name = name;
 70     }
 71 
 72     public Float getMoney() {
 73         return money;
 74     }
 75 
 76     public void setMoney(Float money) {
 77         this.money = money;
 78     }
 79 }
 80 
 81 
 82 package com.ssm.service.impl;
 83 
 84 import com.ssm.dao.AccountDao;
 85 import com.ssm.domaiin.Account;
 86 import com.ssm.service.AccountService;
 87 import org.springframework.beans.factory.annotation.Autowired;
 88 import org.springframework.stereotype.Service;
 89 
 90 import java.util.List;
 91 @Service("accountService")
 92 public class AccountServiceImpl implements AccountService {
 93     @Autowired
 94     private AccountDao accountDao;
 95 
 96     public List<Account> findAll() {
 97         System.out.println("業務層查詢全部用戶");
 98 
 99         System.out.println(accountDao.findAll());
100         return null;
101     }
102 
103     public void saveAccount(Account account) {
104         System.out.println("業務層 保存用戶");
105     }
106 }
107 
108 package com.ssm.service;
109 
110 import com.ssm.domaiin.Account;
111 
112 import java.util.List;
113 
114 public interface AccountService {
115 
116     List<Account> findAll();
117 
118     void saveAccount(Account account);
119 }

用於測試spring mybatis的代碼以下

package com.ssm.test;



import com.ssm.dao.AccountDao;
import com.ssm.domaiin.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;

public class TestMybatis {
    @Test
    public void testFindAll(){
        try {
            InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
            SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
            SqlSession session= factory.openSession();
            AccountDao aDao = session.getMapper(AccountDao.class);
            List<Account> list = aDao.findAll();
            System.out.println(list);
            session.close();
            in.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}


package com.ssm.test;

import com.ssm.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {
    @Test
    public void testFindAll(){
        ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
        AccountService accountService = ac.getBean("accountService", AccountService.class);
        accountService.findAll();
    }

}

在resource文件夾下創建applicationContext.xml springmvc.xml SqlMapConfig.xml jdbcConfig.properties

springmvc.xml內容

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:mvc="http://www.springframework.org/schema/mvc"

    <context:component-scan base-package="com.ssm">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

<!--    視圖解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
<!--    過濾靜態資源-->
    <mvc:resources mapping="/css/**" location="/css/"/>

    <mvc:resources mapping="/images/**" location="/images/"/>
<!--    開啓註解支持-->
    <mvc:annotation-driven/>
</beans>

jdbcConfig.properties內容 mysql用的是8.0版本

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf8&useSSL=false&serverTimezone=UTC
jdbc.username=root
jdbc.password=123456

若是是.xml格式的把&符號改成&amp;

applicationContext.xml 內容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"

        <property name="password" value="${jdbc.password}"/>
    </bean>
<!--    配置sqlsessionfactory工程-->

    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ssm.dao"/>

</beans>

最後一步在web.xml中配置

<?xml version="1.0" encoding="UTF-8"?>

         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
